5*5f634c65SCorentin CharyDescription:
6*5f634c65SCorentin Chary		Set the brightness of the LED. Most LEDs don't
7*5f634c65SCorentin Chary		have hardware brightness support so will just be turned on for
8*5f634c65SCorentin Chary		non-zero brightness settings. The value is between 0 and
9*5f634c65SCorentin Chary		/sys/class/leds/<led>/max_brightness.

22*5f634c65SCorentin CharyDescription:
23*5f634c65SCorentin Chary		Set the trigger for this LED. A trigger is a kernel based source
24*5f634c65SCorentin Chary		of led events.
25*5f634c65SCorentin Chary		You can change triggers in a similar manner to the way an IO
26*5f634c65SCorentin Chary		scheduler is chosen. Trigger specific parameters can appear in
27*5f634c65SCorentin Chary		/sys/class/leds/<led> once a given trigger is selected.
